Petunia plant named ‘Danlittun4’

ABSTRACT

A new and distinct  Petunia  cultivar naned ‘DANLITTUN4’ is disclosed, characterized by having light purple/violet flowers with distinctive dark purple veins, a compact, mounded plant habit and continuous flowering. The new variety is a  Petunia,  normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Petunia sensu Wijsman.

Variety denomination: ‘DANLITTUN4’.

BACKGROUND OF THE INVENTION

The new Petunia cultivar is a product of a planned breeding program conducted by the inventor, Gabriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to produce new Petunia varieties for commercial applications. The seed parent is the unpatented, proprietary seedling variety referred to as Petunia sensu Wijsman ‘CV-688.’ The pollen parent is the unpatented, proprietary seedling variety referred to as Petunia sensu Wijsman ‘CV-82.’ The new variety was discovered in April 2006 by the inventor in a group of seedlings resulting from that crossing, in a commercial greenhouse in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar ‘DANLITTUN4’ by vegetative cuttings was first performed at a commercial greenhouse in Moshav Mishmar Hashiva, Israel in April 2006 and has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DANLITTUN4’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DANLITTUN4’ These characteristics in combination distinguish ‘DANLITTUN4’ as a new and distinct Petunia cultivar:

-   -   1. Small flowers     -   2. Compact growth habit     -   3. Distinctive dark purple throat and veining.     -   4. Suitability for outdoor containers and garden situations.

Plants of the new cultivar ‘DANLITTUN4’ are similar to plants of the parent, Petunia sensu Wijsman ‘CV 688’ in most horticultural characteristics, however, plants of the new cultivar ‘DANLITTUN4’ are more compact and have a different flower color.

Plants of the new cultivar ‘DANLITTUN4’ are similar to plants of the parent, Petunia sensu Wijsman ‘CV-82’ in most horticultural characteristics, however, plants of the new cultivar ‘DANLITTUN4’ are more compact and have a different flower color.

Plants of the new cultivar ‘DANLITTUN4’ are similar to plants of the commercial variety ‘MP19,’ U.S. Plant Pat. No. 12,979 in most horticultural characteristics, however, plants of the new cultivar ‘DANLITTUN4’ have deeper flower coloration, especially with darker veins. The new variety also produces slightly less branches than plants of ‘MP19.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DANLITTUN4’ grown in a greenhouse, in a 16 cm basket. Age of the plant photographed is approximately 90 days from a rooted cutting.

FIG. 2 illustrates in full color a close up of a typical bloom of ‘DANLITTUN4.’

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
